摘要： A haptic device includes a network of motorized shear actuators. The shear actuators each include a drive mechanism and a lead screw having a threaded outer surface rotatably coupled to the drive mechanism and extending along a primary axis. A carriage is movably coupled to the lead screw by a nut having a threaded inner surface and is disposed within a chassis. One or more flexure springs are attached to the chassis and are configured to exert a reactive force to resist a force applied to the carriage in a direction orthogonal to or substantially orthogonal to the primary axis. The flexure springs may cooperate with a stop mechanism to improve the mechanical robustness of the shear actuators under applied loads.

摘要： The disclosed wearable apparatus may include (1) a device dimensioned to fit about a body part of a user, (2) a tensioning mechanism that harnesses to the device in a manner that is relative to the fit of the device about the body part of the user, and (3) an actuator couples to the tensioning mechanism that, when actuated, causes substantially tangential movement of the tensioning mechanism relative to a surface of the body part to produce substantially orthogonal movement of the device relative to the surface of the body part. Various other methods, systems, and/or computer-readable media are also disclosed.

摘要： A haptic device including an active element and a plurality of passive elements coupled to the active element. Each passive element has a respective response to a wave transmitted by the active element, and is configured to cause a respective haptic effect at a respective location away from the active element. In some embodiments, the respective response includes resonating when energy having a resonant frequency is received. In some embodiments, the wave transmitted by the active element is in the form of a vibration or acoustic energy.

摘要： A haptic device is provided that includes a first haptic assembly, comprising (i) a first end effector, and (ii) a first actuator coupled with the first end effector. The first actuator is configured to move the first end effector in first direction(s). The first haptic assembly is configured to create a first haptic stimulation or a second haptic stimulation, felt by a wearer of the haptic device, when the first actuator moves the first end effector in the first direction(s). The haptic device includes a second haptic assembly, comprising: (i) a second end effector, and (ii) a second actuator coupled with the second end effector. The second actuator is configured to move the second end effector in second direction(s). The second haptic assembly is configured to create a third haptic stimulation, felt by the wearer, when the second actuator moves the second end effector in the second direction(s).

摘要： An apparatus for creating and tuning haptic feedback is provided. The apparatus includes (A) a brace with first and second portions, (B) a vibrotactile actuator, coupled to the first portion of the brace, configured to apply haptic stimulations to a user, and (C) a linear actuator, coupled to the second portion of the brace, configured to (i) obtain a signal generated based on information about the user's body at a target location of the user and (ii) adjust a tension of the brace according to the signal. In some embodiments, the apparatus also includes one or more sensors configured to generate the information about the user's body at the target location. Furthermore, a controller may be configured to: (i) generate the signal based on the information about the user's body at the target location generated by the one or more sensors and (ii) provide the signal to the linear actuator.

摘要： A haptic-jamming device may include (1) a first haptic-jamming member having a polarizable first element rotatable about an axis and a first elongated extension outwardly disposed from the first element in a first direction, (2) a second haptic-jamming member having a second element rotatable about the axis and a second elongated extension outwardly disposed from the second element in a second direction, and (3) a variable voltage source for at least one of the first haptic-jamming member or the second haptic-jamming member that, when energized, generates an electrostatic field encompassing at least one of the first or second elements. A level of separation of the first and second elements may be related to a strength of the electrostatic field. Various other methods, systems, and wearable articles are also disclosed.
